Thanks for such a friendly advice from a Furutech seller - although I have many Furutech rodium plugs in my system my interest for NCF vanished.

Wow, really? Sorry for hurting your feelings, but I'm not your personal assistant. Your thoughts that I must take my time to look up info YOU are interested in is RIDICULOUS.

And the thought that your "interest" in Furutech NCF products depends on me taking my time to do research for you is also RIDICULOUS.

This is RIDICULOUS.

Fortunately the majority of other sellers I found in WBF were more friendly.

IMO it is not ridiculous in a subjective hobby that strongly depends on consumer interest and bias to make choices. But it is true that some audiophiles love seller arrogance and authority in critical subjects - they feel protected by it. Not my case. There are brands I will never get because of manufacturer arrogance. This is an hobby supposed to carry happiness and friendship, I only buy from friendly people.

I honestly can't believe your attitude here, you're an entitled little man making ridiculous demands.

Over the years here on WBF you've clearly stated you'd never buy from me or a business like mine, instead you prefer large dealer-sale businesses. Fine. But you seek to belittle me and demean me at any given opportunity, and now I think you've crossed the line into harassment and bullying.

You've gone way off topic and made this personal, it has been reported to mods stop any further nastiness from you.

For me an entitled little man is someone who writes insults in posts in capitals. Sorry to disagree with you.

You have short memory - my comments were mostly due to the fact that I live in Europe and returns are not possible to small US brands due to taxes and customs. I even send a message to you asking if you had distribution in European Community and you said unfortunately no. I have bough from small local manufacturers, although yes, I prefer the safety of local distribution.

I am sorry you see i in such way. You addressed some information that seemed very interesting and I could not find, I asked for it.

He thinks resistance is the ONLY thing that matters.

This statement is false. It might be closer to the truth if 'impedance' were used instead of 'resistance;, and 'noise, distortion and bandwidth' were added to it.

You're trying to do anything you can to disparage me, and you've done this for years if not a decade +, your hate apparently knows no bounds and you keep grudges in perpetuity. This is really sad.

And you're blatantly lying about living in Europe and returns, you said straight up you'd never buy from a business like mine, instead finding products from larger dealer-sale businesses to be more credible.

I made it personal with MY arrogance? You're the one who thinks I should be your personal assistant! I charge $200/hr labor and consultation, if you'd like to pay me we can talk. The thought I'm somehow responsible for providing you information is arrogant? You are absolutely nuts micro.

Are you going to go to the trouble to correctly set up a battery system and then a/b lead acid and LIFeP?

I certainly wouldn’t want lead acid batteries in my listening space just for safety reasons alone!

Unless you’ve heard from a reliable source that lead acid sounds better, I wouldn’t waste my time.

I will go for AGM lead acid battery but I think I should ask Friedrich Schaefer to help me for correcting battery sound with capacitors or dc filters.

 

[Amir]

Why? Can you give me any reasoning or tell me what you think is far better?

You think YOUR solution is anywhere near good? It's NOT. I know because I'VE DONE IT MYSELF. You have no clue what you're talking about and I've been reading your comments and literally laughing.



Apparently you didn't read the rest of my post. There's some info right here on WBF if you want to look it up.

I checked more than three furutech ac distributors , all of them were awful.

You sell furutech so you can laugh to others who do not like furutech products.

AC regeneration solution, both Kevin (Living Voice designer) and Romy use AC regenerators.

What is "awful"? That means nothing to anyone except demonstrating your own bias.

AC regen can certainly work, but you obviously have no clue about using batteries so why do you think you know anything at all about passive noise reduction?

I tried AGM batteries well over a decade ago, and then I designed a filter system for it after realizing it has it's own type of noise and it's output impedance is too high. This is not a bad solution IF your AC power is really bad to begin with, but I think the simplest solution that works is the best way to go.

Most Furutech products change the sound in a wrong direction, for example their cables increase the bass or furutech filters or distributors decrease dynamics for more black background. I think those are awful.

Read my posts, I never said using battery victron inverter is perfect solution, I just try to find a better way.

 

[Maryland]

FWIW, I can have Torus factory loaded with Furutech outlets. OMG. A GTX duplex at the wall with a custom power cord to a RM20. A GTX outlet in the first position in the RM20 going to a Furutech power strip with RF coating inside. I bet that would be out of this world better than most any filter setup.

Do you think the RM20->Furutech strip would be substantially better than just an RM20 loaded up with Furutech NCF outlets?

Not one person who has actual experience with these products thinks what you said is accurate.

As some said before "You can't handle the truth" ...

This is a public free forum - if you make technical claims in WBF you are supposed to support it. Just IMO , YMMV.

This statement appears false as well; citation is required.

Amir. Use Lithium. Here is why.
1 energy density. To get 100AH of storage, your going to need about 3 x 100 lb batteries. A.single 100 lb lithium will equal the same storage.

2nd and more important. You can draw a lithium battery down to 20% charge around 3000 times.
You can only draw led acid down to 50%. And it might only do it 500 times.
This has major cost and performance implications. For one, to have 100 AH of power, you would actually need about 160AH of led acid battery. Do the math. 100 AH to 20 AH vs 100 AH to 50 AH.

Lithium is also very voltage stable till you get to about 10% left. Then it falls off very fast. A led acid is a steady decline of voltage.

When you math the cost of how many batteries you would need, how little you can discharge them and how quickly they need.to be replaced, lithium is the same price as led acid. Maybe less.


AND, led acid should be stores in a vault where any leaking gasses are discharged. This is not as much an issue with AGM. But it is absolutely a building and nec code requirement for wet batteries.

Just get lithium. Buy Abyss Batteries. Marine grade. Excellent internal BMS protection. Good support. Get the 105AH 48 volt golf cart battery.
I am a dealer, but I can't help you. Write them direct. I can show you how to fuse and cable them to the inverter. I have good all copper, silver plated 100A disconnect plugs to use in the cabling to make moving things around in the room easy. Get FTZ Marine compression lugs. Deoxit all your connections.

Edit, Lithium charges much faster. You can dump power into a lithium.

[Kingrex]

I think you can hear a battery, not because of the battery. More that a lithium has a much higher instant discharge rate. The inverter may experience less lag in current delivery if the battery has more available power.
I am trash talking as I don't know if this is or is not the case with an inverter. People also tell me the cable from battery to inverter also has a voice. I would assume for similar reasons.

 

[Kingrex]

Dave also has me wondering if I don't want to encapsulate the FET in the inverter with 3M RF shielding. Keep that noise out of the boosting transformer.

What’s the reasoning by going with an AGM battery other than it being less expensive? A LifePo shows better performance on a # of metrics.

It may not even be less expensive when you consider what I noted in post 176. People into Solar use Lithium. They are very much into least cost for energy storage. Its also less cables, connectors etc as you need less batteries.

The only other options I would consider, especially being in Iran, Sodium Ion batteries. They seem to be available there. Being used in utility scale systems as well as in some cars. The density is not the same as lithium. But, they basically last as long. 3000 to 4000 charges. Discharge to 20%. They don't emit toxic gas. They don't catch fire. They are the same size as led acid. They are $1500 plus a charger in the US. I am actually curious now. I found one dealer in the US.
